Changing the default superuser
You can change the default superuser from the default cassandra user.
By default, each installation of Cassandra includes a superuser account named
cassandra whose password is also cassandra. Superuser permissions allow creation and
deletion of other users, and the ability to grant or revoke permissions.
Note: Use the default cassandra user only to assist with initial setup
of new users and superusers, and then delete it.
- Logins for the cassandra user are performed with QUORUM
consistency.
Do not use the cassandra user in production, because QUORUM consistency has significant performance degradation for multiple data centers.
- Logins for all other users are performed with LOCAL_ONE consistency.
